Starting with 10.2 we put all our new DB on ASM. That include a few TB DWH, and other critical systems. There is some downsize due to the fact that the OS does not know whats inside:
1) Tivoli from IBM can not monitor that space inside the volumes assigned to ASM, so we have to develop our own scripts for this. 2) Tivoli TSM (backup to tape) can not backup the files.

As hands on dba, who mostly learn what he needs to operate that piece of machinery, I started to use ASM without much investment.
